Two things:
1)Resolution is amazing and I mean truly amazing. Thanks for the PE II recommendation as the kids love those shows and they are visually breathtaking. (Different subject, but check out Chef's Table. It's a well shot show with great visuals.)
2)The footprint is almost nothing. It's a 55" TV with almost no boarder, making for an "all picture" experience. The image seems like it is just hovering in space.

$360 shipped with Prime. I think these specs would have cost twice as much maybe 18 months ago. It's pretty amazing.

...and it was almost 3 times what you paid. When we sold the house, we left the new owners our 110" home theater projector image and I thought I'd miss it terribly. But we're very happy with our 55 in our apartment - in fact, we love it and hope you enjoy yours as much!

There is no pleasure worth forgoing for an extra three years in the geriatric ward.

I sit ~10-11 feet away and have gotten used to the size to the point it feels small now. I only watch movies or 'epic' TV shows (as in, big budget, basically made like movies), which are things that want a BIG screen. Never watch standard TV or TV with ads (which are not great on a massive screen).

I cannot do a projector, and secretly wishing mine would die so I had an excuse to step up. 77" LG OLED would be nice, but might trade some picture quality for size with one of the 82/85/88" panels.

Check out 'Wild Pacific' or 'South Pacific' (same thing, different names for different markets). The visuals are just unreal. They spend more time above water than underwater, and it is just unreal.
